<h2>Ceph 依赖<a class="headerlink" href="#ceph" title="Permalink to this heading"></a></h2>
<p>按常规来说，我们建议在较新的 Linux 发行版上部署 Ceph ；同样，要选择长期支持的版本。</p>
<section id="linux">
<h3>Linux 内核<a class="headerlink" href="#linux" title="Permalink to this heading"></a></h3>
<ul>
<li><p><strong>Ceph 内核态客户端</strong></p>
<p>如果你在用内核客户端映射 RBD 块设备或挂载 CephFS ，
那么一般来说，内核客户端机器应该使用由 <a class="reference external" href="http://kernel.org">http://kernel.org</a> 或者发行版提供的“稳定”或者是“长期维护的”内核系列。</p>
<p>对于 RBD ，如果你想<em>紧跟</em>长期内核，
我们建议用最低基于 4.19 的“长期维护”内核系列。
如果可以用更新的“稳定版”或者“长期维护”的内核，那更好。</p>
<p>对于 CephFS ，选择内核版本时可参考<a class="reference external" href="../../cephfs/mount-using-kernel-driver#which-kernel-version">用内核驱动挂载 CephFS</a>。</p>
<p>较老的内核客户端可能不支持你的 <a class="reference external" href="../../rados/operations/crush-map#tunables">CRUSH 可调值</a>配置、
或 Ceph 集群其它比较新的功能，这样的话，
就得关闭存储集群上的这些功能。对于 RBD ，
要想获得比较完整的 RBD 映像功能，内核版本最低是 5.3 ，
或者最低用 CentOS 8.2 。</p>

<h2>系统平台<a class="headerlink" href="#id2" title="Permalink to this heading"></a></h2>
<p>下面的表格展示了 Ceph 为哪些 Linux 发行版提供二进制软件包，
Ceph 在哪些平台上测试过了。</p>
<p>Ceph 并不依赖特定的 Linux 发行版，它可以运行在任何发行版上，
只要包含支持的内核和系统启动框架，比如 <code class="docutils literal notranslate"><span class="pre">sysvinit</span></code> 或者 <code class="docutils literal notranslate"><span class="pre">systemd</span></code> 。
Ceph 有时也会被移植到非 Linux 系统上，但那不是核心团队的关注点。</p>
